SYSTEM FOR MANUFACTURING INTERSTITIAL RADIATION THERAPY SEED STRANDS

摘要

A delivery system and method for interstitial radiation therapy comprising substantially axially stiff and longitudinally flexible elongated members made of material which is bioabsorbable in living tissue and a plurality of radioactive seeds (308) dispersed in a predetermined array within the elongate member. The radioactive seeds can be dispersed within assembled half-shells (301A, 301B) made of the same material. The housing for the radiation seeds can also be manufactured from extruded material. A system (322) for manufacturing the interstitial radiation therapy seed strands that automatically makes the seed strands at the patient's bedside also includes a robotic arm (326), sotware controller (328), and computer (330). The delivery system and method further customize the seed strands based on a prescription.
